being had to the accompanying drawings,-

tformin g a part of this specification, and to the no lettersof reference marked thereon.

This invention relates to improvements in brush-machines, the objects of the invention being to provide an improvedmechanism for automatically presenting the blocks consti- 5 and at the proper angle to the cooperating tool, which latter may be an inserter or filler for inserting and anchoring the bristles or tufts of bristles or a tool for forming the tles.

:I have shown the present improvements in 1 connection with a filling-machine of a wellknown type, and asjthe details of the' same form no part of the invention it will not be described in detail, especially as it is to be understood that the invention may be used in connection with-the mechanism shownor other preferred or well-known mechanisms sitioned with relation thereto. I

The invention consists incertain novel details of construction and combinations and arrangements of parts, all as will be now de- 335 scribed, and pointed out particularly in the appended claims. I

In the accompanying drawings, Figure 1 is "a perspective view of a machine embodying the present improvements.

moving the block-carrier. Fig. 3 is a similar view of another part of said mechanism. Fig. 4 is a view of the feed and partof the stop mechanism. Fig. dis a detail of the clutch and its operating-lever. Fig. 6 is a tuting the brush-backs in proper position holes or sockets for the reception of the brisfor operating on the block when properly pol The pivots or axes on which the carrier-frame Fig, 2 is a per- 0 spective view of a partof the mechanism for is a type of machine now on the market and known as the Frazier filling-machine. It embodies a stand or base-frame A and a superframe B, the latter having suitable bearings and supports for the filling mechanism proper. The major portion of the filling mechanism proper is contained in or supported by a head O and is operated by a horizontally-arranged drive-shaft O, carrying a drive-pulley O at the rear end, to which power may be applied from any suitable source. Through the operation of this filling mechanism the bristles are advanced to an inserter D and by the latter'inserted and anchored in suitable sockets previously formed in a block or brush-back when the latter is presented in proper position for codperation with the inserter. For the purpose of positioning the block the latter is mounted on a carrier E, 1

where it is clamped by suitable clamps e of any Well-known form,which will properly center and hold the blocks while being operated upon. The carrier ismo unted on or constitutes part of a frame, the remaining portion of which is formed by downwardly-extending rods E, adjustablyrmounted at their lower ends in bearings on a shaft E and the latter is journaled in a-second frame F, having a downwardly-extending support F, pivoted in and guided by a vertically-adjustable frame G.

and secondary frame swing are arranged at right angles to each other, and while the radiu's of the are described by-the carrier with the shaft E as a center may be varied by adjusting the rods E the radius of the are described by the carrier by the swing of the sec- .ondary frame is preferably made adjustable by providing ,a series of holes f in the support F and a corresponding series of holes the formation of symmetrical brushes of oblong or elongated shape. a

For controlling the position of the carrier two pattern-cams (lettered H) are provided, both preferably mounted on a cam-shaft h,and independent mechanism is interposed between said cams and carrier,each of said mechanisms serving to position the carrier in an arc the plane of which is at right angles to the other. For positioniri'g the carrier with the shaft E as a center said carrier is provided with guides or rods I, extending therefrom at each end, said rods working in vertically-extending slots or guideways I in the forward ends of controller-frames 1 The latter are movable longitudinally, being for this purpose mounted at the forward ends in swivelblocks 't', adjustable on rock-arms 'i, and at their rear ends on arms K, rigid on a transversely-extending rock-shaft K, Fig. 2. shaft K is provided with an arm K having a roller k adapted to rest on one of the pattern-cams, the connection between the arm and shaft preferably being made adjustable through a segment K rigid on the shaft, and an adjustable connection, as set-screws K between the segment and arm. The arm K and cam .will thus effect the movement of the carrier on one center, but at the same time the carrier is free to swing on the other center, because of the elongated slot or guideways on thecontroller-lframes and along which the guides are free to travel, this mechanism constituting one operating mechanism for moving the carrier in one are and for guiding it in its movements in the other arc. The movement of the carrier on these guideways or in the plane of the other arc is effected through the medium of a controller rod or guide L, located beneath the carrier and working in the forked end of a second controller-guide M, the latter being carried by one arm of a bell-crank lever M, Fig. 3', pivoted on the machine-frame and connected by a link M with the upper end of an arm N, journaled on the shaft K. Also j'ournaled loosely on said shaft K is a second arm N", corresponding to the arm K but adapted to cooperate with the other pattern-cam and adjustably connected with the arm N by setscrews 71, as shown. This mechanism constitutes the other operating mechanism for moving the carrier in the other are and for guiding it while being moved by the other operating mechanism. The cams, it will thus be seen, control the movements of the carrier in both arcs, and said cams may he so formed as to properly position any shape of brushback for the insertion of bristles at any desired angle, or if a socket-forming tool be substituted for the inserter the sockets may be correspondingly formed.

In the ordinary operation of the machine a back having the sockets therein is usually clamped in the carrier and the latter moved by hand, such movement being utilized to position the ends of the arms K and N, and by The marking from the latter or by substituting cutters for the rollers the cams may be readily formed from suitable blanks. Obviously when the pattern-cams have been formed they will position other blocks exactly in accordance with the master-block from which the cams were formed.

The frame G, in which the secondary frame F is journaled, is preferably vertically adjustable on guides 0, such adjustment being effected by a screw 0 in rear of the frame G, (see Fig. L) and to further guide said secondary frame and relieve the pivot-pin the upper edge of the frame G is formed into a curved guide G, and the support F is provided with a roller F adapted to bear on said guide in the movements of the carrier from side to side. This guide assists in keeping the face of the brush-block the same distance from the inserter and is changed from time to time, as required to suit the different arcs.

For imparting intermittent motion to the pattern-cams the cam-shaft is provided with a worm-gear P, Fig. with which meshes a worm P, carrying a ratchet-wheel P and a hand-wheel P J ournaled on the worm-shaft is an oscillatory pawl-frame P, carrying a pawl 19, held in engagement with the wheel by a spring-pin p, bearing against a flat face on the pawl-stud 19 the arrangement being similar to that in my prior patent, No. 666,217, dated January 15, 1901. The pawl-frame is connected by a link Q with the lower end of alever Q,pivoted at the upper end to a bracket Q on the main frame and having at an intermediate point a roller or stud (1, working in a cam-groove in a cam Q on the main driveshaft.

The pulley 0 is connected with the shaft 0 by a clutch adapted to be released automatically when the pattern-cams have reached a predetermined position-as, for instance, when the block has been completely filled. In the preferred construction the clutch is formed by a spring-pin R, carried by a collar or disk It, rigid on the shaft, Fig. 5, and adapted to enter a semicircular recess in a flange or disk on the pulley, and a trip in the form of a wedge S, adapted to engage the pin to press it back and out of the recess, is provided fordisconnecting the clutch. This trip is supported by the frame and moved out of the path of the pin by a spring S and into the path of the pin by a bell-crank shiftinglever T, one arm of which is connected with an operating-rod T, extending down into position for its lower end to engage and be operated bya stop projection T carried by the pattern-cam shaft. The extreme end of the operatingrod is preferably jointed at T whereby reverse movement of the shaft may take place Without affecting the clutch, and what is of greater importance when the parts come to rest with the rod resting on the projection the end of the rod may be moved by hand out of engagement with the projection to release the rod and permit the reengagement of the clutch without the necessity of moving the pattern-cams and shaft on which the stop projection is mounted. Any lost motion is taken up and the control-arms held against the cams by springs or weights. Thus springs U serve to hold the frames 1 forward, and a weight U, connected with the secondary carrierframe by a flexible connection passing over a pulley U serves to hold the carrier pressed in one direction, therebypreventing play should any of the joints or bearings become loose or worn. i g

In operation the attendant places a block in the carrier and clamps the same firmly in place. Thus to inaugurate the movement of the machine he advances the cam-shaft a short distance or moves the end of the clutchrod out of engagement with the stop T there.- by releasing the clutch. The movements of the parts are so timed that the block is positioned and comes to rest before the inserter or cooperating tool operates thereon, and the movement of the block and carrier to a new position takes place after the said inserter or tool has withdrawn from engagement with the block. The positioning mechanism is simple and effective, and when a block has been operated on the parts are left in position for beginning to operate on a new block, thereby avoiding the necessity of a reverse or return idle movement of the parts in order to reach the starting position.

It will be observed that the carrier has guides which are arranged at right angles to each other, each of said guides operating to move the carrier in one are or on one of its centers and to guide the carrier in its movements on the other arc or on its other centerthat is to say, if one pattern-cam only were operated the carrier would be swung in one direction only and the motion would be transmitted to the carrier by the guide'controlled by that cam; but the other guide would operate to prevent movement of the carrier in any other direction, because its operating mechanism would be fixed andtheguide would slide thereon. This construction is simple and highly efiective, inasmuch as it brings the control mechanism directly into engagement with the carrier.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
